January 13.
4:00 PM (January 12. In the Midwest, it is 2:00 AM on the 13th.) sharp.
At the Mitsukoshi Department Store in Keijio, Miyoko Maki put on his gas mask in the men's restroom on the 2nd floor. He'd then walk by a designer clothes store, and then punctured the one of the 4 filled with Sarin with a pen he had on him. He'd then travel up the other 3 floors, where he punctured each of the 3 bags he had left.
Due to the previous 3 attacks, there were very few people in the building, and therefore, only 25 would die of the gas, and 84 others were infected, but survived (Not counting the infected that were killed in the bombing). But, this was not the end.
Miyoko, now noticing that his gas mask was faulty, quickly attempts to inject the antidote into himself, only for him to drop it off the roof. In one last blaze of glory, he detonated the bomb in his car, a 2002 Hyundai Avante, which killed 15 and wounded 39, before jumping off of the balcony, killing himself, and 1 other person, which he fell on.
In total, 42 were killed and 123 were wounded.
2 hours and 9 minutes later (12:09 PM Constantinople time), Turkish Airlines Flight 917, a Boeing 777-300ER, registration TC-JJH, with 400 passengers and 14 crew, took off from Constantinople, bound for Casablanca.
At 12:17 PM, the 3 hijackers, Halit Bilgi, Rahman Hamdi, and Toydemir Yagci got up from their seats at 1D, 1E, and 1G. A flight attendant, Gulsu Sulak, attempted to stop Halit, but he told her that he was going to the restroom, she tried to block the exit, and so he stabbed her, severely wounding her and causing her to die approximately 5 minutes later.
Rahman then kicked down the door, and Toydemir and Halit dragged pilots Polat Gulen and Akdogan Alptekin out of the cockpit. Polat was killed first, and Akdogan proceeded to fight the hijackers, managing to kill Rahman with a blow to the throat, before being killed too.
Toydemir marched off, taking control of the aircraft at 12:20, and started to turn the plane around towards Izmir, and set the transponder to 7500, the code for hijacking, as a way to taunt ATC.
He also kept conversing with other planes in the area, primarily SunExpress Flight 9184 and 958. He mostly talked about how they were next, and sometimes tried to turn towards them, as if they were about to collide.
At 12:31, Flight 917 crashed into Building A of the Folkhart Towers in Izmir, known for being the headquarters of the Constantinople Administration Commission. Flight 917 hit below the floors where it was headquartered, between the 15th and 20th floors, and trapping everyone above the impact site, killing all 414 people on board, plus 1,220 on the ground. 361 were also wounded when the building collapsed at 12:47.
An hour and 59 minutes later, at 2:24 AM (LA Time), Sun Country Airlines Flight 430 takes off from Los Angeles-Proaño. It was a Boeing 737-800 with 183 passengers and 5 crew. Its registration was N804SY.
At 2:27, the 3 hijackers, Orville Farmer, Randall Holt, and Neal Andrews rose up from their seats at 1A, 1B, and 1C, and forced the 2 pilots, Christopher Hicks and Spencer Vaughn, out of the cockpit. The entire hijacking was relatively peaceful compared to the bloodbath aboard Turkish Airlines 917, which left 4 dead, with Farmer using the threat of murder instead of murdering.
Holt and Andrews then moved everyone to the back of the plane, as Farmer took the controls. The plane shook as Farmer attempted to not hit a helicopter about ready to land at their target: The US Bank Tower in Los Angeles.
But, they couldn't, and the wing collided with the helicopter, destroying it and killing the pilot, Owen Olson, at 4:29, before slamming into an area between the 25th and 18th floors in the US Bank Tower, killing all 188 people on board.
The plane didn't destroy the stairs like in Constantinople, but it did sever elevator shafts, causing elevators to plummet, often times killing its occupants.
This attack also killed 340 and wounded 663.
